The burying method comprises the following steps that (a) holes are drilled; (b) slurry is continuously filled in drilled holes for hole washing after the hole drilling completion; and (c) after the hole washing completion, a prepared inclination measuring pipe is inserted into the drilled hole, the bottom end of the inclination measuring pipe with an end cover is firstly downwards placed into the drilled hole, clean water is fully filled in the inclination measuring pipe, the upper section of inclination measuring pipe is connected, the insertion is continuously carried out after the connection completion, the operation is repeated in such a way until the inclination measuring pipe is inserted into the hole bottom, the rest inclination measuring pipe is cut off, the distance from a pipe opening of the inclination measuring pipe to the ground is 200 to 500mm, the pipe opening of the inclination measuring pipe is sealed and covered by a top cover, and the gap of the drilled holes outside the inclination measuring pipe is filled by sand or bentonite. The burying method has the advantages that the inclination measuring pipe burying is convenient, the construction speed is high, the cost is low, the inclination measuring pipe and the surrounding soil body can be enabled to form a whole after the burying, the inclination measuring pipe can deform along with the horizontal displacement of the soil body, and the horizontal displacement of the soil body at the position is analyzed and obtained through measuring the horizontal deformation of different positions of the inclination measuring pipe.
Description
Technical field
The present invention relates to the deviational survey pipe, especially relate to the method for burying underground of the deviational survey pipe of foundation ditch safety monitoring or sloping body monitoring usefulness.
Background technology
Along with the development of urban construction, high-rise super highrise building, subway etc. all relate to the construction of foundation ditch, have along construction for guaranteeing foundation ditch safety, and the deformation monitoring of foundation ditch is a requisite job in the foundation pit construction.The horizontal movement of measuring the foundation ditch periphery soil body in the foundation pit deformation monitoring is to judge important content of foundation ditch safety.In the soil mass of foundation pit digging process; Space enclosing structure (fender post, diaphragm wall etc.) is with soil excavation; Broken the inside and outside stress balance of space enclosing structure; The sliding deformation that occurred level distortion under the space enclosing structure lateral earth pressure effect outside, the displacement of space enclosing structure occurred level cause the soil body in its outside to produce trace, the deviational survey pipe that is embedded in this moment in the soil body also produces displacement with the distortion of the soil body; The distortion of adopting the special measurement instrument can measure deviational survey pipe different depth, the horizontal movement of soil body different depth just.Burying underground of deviational survey pipe is a link on basis in this surveying work, is the prerequisite and the basis of soil body deep horizontal displacement measurement.Therefore how to accomplish burying underground of deviational survey pipe, the degree of depth that the deviational survey pipe is inserted to designing requirement becomes the most important thing.
The deviational survey pipe is buried underground by conventional method and is had the gap between deviational survey pipe and the soil body after accomplishing, and can not reflect the horizontal movement of the soil body exactly through deviational survey pipe data measured; The deviational survey pipe is buried complicated operation underground, and speed of application is slow; The mouth of pipe often is capped or vehicle rolls, and is damaged, and work causes difficulty to deviational survey, and serious can't carry out deviational survey, causes the disappearance of deviational survey data.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art; Provide a kind of assurance deviational survey pipe and the tested soil body to be integrally formed; Cooperative transformation through measuring the horizontal distortion of deviational survey pipe different depth, can be extrapolated the horizontal movement of soil body different depth; Predict safe condition in advance, in time take measures to prevent the method for embedding of deviational survey pipe in the soil body of the generation of security incident.
The method for embedding of deviational survey pipe of the present invention in the soil body, it may further comprise the steps:
(a) boring, position, hole misalignment of axe is not more than 100 ㎜;
(b) continue in boring, to annotate mud after boring is accomplished and carry out hole flushing;
(c) immediately ready deviational survey pipe is inserted in the boring after hole flushing finishes, the deviational survey pipe has the bottom of end cap and inserts boring down earlier, stops during the 0.5-1 rice of end distance ground on the deviational survey pipe; In the deviational survey pipe, fill clear water, connect a last joint deviational survey pipe, connect the completion continued and insert; So repeatedly at the bottom of being inserted to the hole, with the amputation of unnecessary deviational survey pipe, inclinometer tube orifice 200～500 ㎜ above ground level; Inclinometer tube orifice is built with top cover and is sealed, and fills the gap of the outer boring of deviational survey pipe with sand or swell soil.
The advantage of the inventive method is: deviational survey pipe installation site is accurate, and the soil deformation data that measure can reflect foundation ditch periphery deformation behaviors of soil, judges that for correct the safety of foundation ditch provides foundation accurately and reliably; The deviational survey pipe is buried underground conveniently, and speed of application is fast, and cost is low; Deviational survey pipe and surrounding soil after guaranteeing to bury underground form an integral body, and the deviational survey pipe can be out of shape with earth horizontal displacement, through measuring the horizontal distortion of deviational survey pipe diverse location, analyze the horizontal movement that draws this position soil body; Around the mouth of pipe, build a corral wall, line up is protected, and prevents to collide when plant equipment or vehicle from passing through the deviational survey pipe, covers the mouth of pipe during article such as stacking material.
The specific embodiment
Below in conjunction with instantiation the present invention is done to describe in detail.
The method for embedding of deviational survey pipe of the present invention in the soil body is characterized in that it may further comprise the steps: (a) adopt well-digging equipment or borings such as geological drilling rig, jumbolter, position, hole misalignment of axe is not more than 100 ㎜; Constantly in the hole, inject mud in the boring procedure, utilize mud that the silt particle in the hole is taken out of outside the hole; (b) continue in boring, to annotate mud after boring is accomplished and carry out hole flushing; (c) immediately ready deviational survey pipe is inserted in the boring after hole flushing finishes, the deviational survey pipe has the bottom of end cap and inserts boring down earlier, stops during the 0.5-1 rice of end distance ground on the deviational survey pipe; In the deviational survey pipe, fill clear water, connect a last joint deviational survey pipe, connect the completion continued and insert; So repeatedly at the bottom of being inserted to the hole, with the amputation of unnecessary deviational survey pipe, inclinometer tube orifice 200～500 ㎜ above ground level; Inclinometer tube orifice is built with top cover and is sealed, and fills the gap of the outer boring of deviational survey pipe with sand or swell soil.
After accomplishing described step (c),, around the deviational survey pipe, build a corral wall, and perform the visible marking, prevent to collide inclinometer tube orifice in the work progress, cause the deviational survey pipe to damage for protection deviational survey pipe.During each the measurement mouth of pipe top cover is opened, measurement is in time sealed the mouth of pipe after accomplishing, and prevents that foreign material from getting into obstruction deviational survey pipe in the pipe.
